When parking in San Francisco, you should always curb your wheels. If you can’t tell whether you’re pointing uphill or down, just pour out a little water from your bottle into the gutter.

The way the water goes tells you which way the hill goes. Or just look at what all the other drivers on the block did. Easy peasy, right?

The driver of this VW Cabrio made the wrong choice, so a ticket from SFMTA was the result.Parking Control Officers will spot this infraction from a block away and then make a special trip just for you.
